What is the solution to log (9x)-log2^3= 3?
olga_2 [115]

For this case we have that by definition of properties logarithm is met:

log_ {b} (x) -log_ {b} (y) = log_ {b} (\frac {x} {y})

So, rewriting the expression we have:

log (\frac {9x} {2 ^ 3}) = 3\\log (\frac {9x} {8}) = 3

By definition of logarithm we have to:

log_ {b} (x) = yis equivalent tob ^ y = x

So:

10 ^ 3 = \frac {9x} {8}\\9x = 8 * 10 ^ 3\\9x = 8 * 1000\\9x = 8000\\x = \frac {8000} {9}

ANswer:

x = \frac {8000} {9}

How much would you pay for 115 minutes?
melomori [17]

Answer:

Answer is A - $43.40

Step-by-step explanation:

For 115 minutes, we would be in the middle territory and so will need to use the middle equation:

c(x)=0.35x+3.15\\c(115) = 0.35(115)+3.15\\c(115)=40.25+3.15\\c(115)=43.40

Graph the line with slope 3 passing through the point( 2,3) .
givi [52]

Answer:

The graph is shown below.

Step-by-step explanation:

Given:

Slope of line =3

The line passes through the point (2,3)

To graph the line.

Solution:

In order to graph the line, we will first find the equation of the line.

Using point slope equation of line:

y-y_1=m(x-x_1)

where m represents slope of line and (x_1,y_1) represents the point on the line.

Plugging in the slope and the point given in the equation.

y-3=3(x-2)

Using distribution.

y-3=3x-6

Adding 3 both sides.

y-3+3=3x-6+3

y=3x-3

Thus, we can graph the equation of the line.

When x=0

y=3(0)-3

y=-3

Point (0,-3)

We have two points (2,3) and (0,-3) to graph the line.
